.SH NAME
std::experimental::simd_abi::fixed_size \- std::experimental::simd_abi::fixed_size

.SH Synopsis
   Defined in header <experimental/simd>
   template< int N >                      (parallelism TS v2)
   struct fixed_size {};

   The simd_abi::fixed_size<N> tag type ensures data-parallel types to store and
   manipulate N elements (i.e. simd<T, simd_abi::fixed_size<N>>::size() returns N). An
   implementation shall support at least all N ∈ [1, 32]. Additionally, for every
   supported simd<T, Abi>, where Abi is an implementation-defined ABI tag, N = simd<T,
   Abi>::size() shall be supported.

.SH Notes

   An implementation may choose to forego ABI compatibility between differently
   compiled translation units for simd and simd_mask instantiations using the same
   simd_abi::fixed_size<N> tag. Otherwise, the efficiency of simd<T, Abi> is likely to
   be better than simd<T, fixed_size<simd_size_v<T, Abi>>> (with Abi not an instance of
   simd_abi::fixed_size).
